This is not to pick on people for their eduction level, it's just an observation I made a while ago. I used to work at CompUSA in the software department when I was going to school. This was back when the original Doom was a huge hit.
I found that people who had at least some college education often recognized the name "id" and knew it was a reference to Freud. Psychology is a required course at most universities and you just can't teach it without covering Siggy. So when someone would pronounce id's name correctly I'd ask if they had taken a psychology course, and most of the time they had. The customers who had no college background were much more likely to ask me "Where can I find that game Doom, you know the one from I-Dee?".
To me, this was a lot like cache. Computer geeks know it's "cash", but joe sixpacks almost always get it wrong by pronouncing the "e" on the end. So when I was talking to someone I could tell roughly how much they knew about computers just by the way they pronounced cache.
